Why Choose the IMO RXP/0T-3B Photo-Electric Switch?
The IMO RXP/0T-3B is a versatile polarised retro-reflective photoelectric sensor with integrated timer functionality, designed for reliable non-contact object detection in industrial machinery and automation systems. Part of the rectangular RX sensor family, it combines a long sensing range, relay switching output and flexible AC/DC power supply in a compact industrial housing.
Using a polarised optical system and a suitable reflector, the RXP/0T-3B provides a nominal sensing distance of 6 m. Polarisation helps the sensor discriminate between light returned by the reflector and unwanted reflections from shiny targets, making it particularly useful for conveyor, packaging and material-handling applications involving reflective objects.
The RXP/0T-3B operates from 20–60 V DC or 20–253 V AC and provides an SPST NO/NC relay output. Unlike the standard RXP/00-3B version, this model incorporates adjustable timer functions for delay-on, delay-off and one-shot operation, providing additional flexibility when integrating detection signals into industrial control sequences.

Timed Polarised Retro-Reflective Detection for Industrial Automation
Polarised retro-reflective sensors transmit a beam towards a reflector and monitor the returned light. When a target interrupts the optical path, the sensor changes its output state. The polarising system improves discrimination between the intended reflector signal and direct reflections from shiny objects, helping maintain dependable detection in challenging industrial applications.
The integrated timer distinguishes the RXP/0T-3B from the non-timed RXP/00-3B and enables delay-on, delay-off and one-shot switching functions. Combined with the relay output, multi-voltage AC/DC supply and adjustable sensitivity, this makes the sensor suitable for applications where the detection signal must be conditioned or delayed before controlling downstream equipment.
Typical Applications
- Industrial conveyor object detection.
- Packaging and production machinery.
- Material handling and transfer systems.
- Detection of shiny or reflective products.
- Presence and position monitoring.
- Timed object detection and machine-control sequences.
- Automated manufacturing and assembly equipment.
- PLC and industrial control-system inputs.
